As this piece is quite beautiful, there are few things that should be changed or could impact a lot more if changed.

With photography, you always need a focal point, especially one that you recognize rather quickly. Focal points are things that draw your eye: things in the center, things that aren't as blurred as the rest, bright colors, etc. But with this piece, I could not see which was the focal point: the background, or the water droplet.Although I am assuming the water droplet was the main focal point, the fact that the background is so big and bright is the reason takes away from the water droplet and makes the background seem like the focal point.
